The weeks and months leading up to E3 are rife with rumors and speculation, and this year has certainly been no different. We're still several days away from E3 2018, and a number of surprise announcements have been inadvertently revealed ahead of the show thanks to various leaks, with more seemingly trickling out by the day.

Even Nintendo's notoriously tight-lipped nature hasn't prevented rumors and leaks from spreading. Before Let's Go Pikachu and Let's Go Eevee were formally unveiled, rumors had swirled that Switch's Pokemon RPG would be inspired by Pokemon Yellow and launch this November--both of which turned out to be true. Similarly, speculation has been rampant that the massively popular Fortnite would be revealed for Switch at E3. That would make for a truly surprising announcement, although its impact may have been diminished now, as a Switch version of Fortnite was listed by the Korean ratings board.
